Description
Technical field
The utility model belongs to high-tension electricity test device field, particularly relates to a kind of plug-in type insulation bar.
Background technology
High-potting often can use insulating bar, and it is 1.0 meters that insulating bar often saves length, needs to connect some joint insulating bars during test according to physical length, and insulating bar connection of the prior art is threaded connection.Needing hand to twist during two joint insulating bars connections makes it rotate, and because connecting thread is yielding, dirty or blocking, causes two joint insulating bars connect inconvenience or easily occur stripped thread phenomenon, causes inconvenience to onsite application.
Utility model content
The purpose of this utility model is to provide a kind of plug-in type insulation bar, and the utility model structure is simple, makes the thread connecting mode of insulating bar of the prior art into inserting mode, effectively easy to use.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Plug-in type insulation bar, described insulating bar comprises inserted link and extension bar, and plunger end is fixedly connected with plug, and extension bar end is fixedly connected with joint, the plush copper of plug and the groove fit of joint.
Preferably, described plush copper is provided with groove, is provided with rubber ring in groove, rubber ring and groove clearance fit.
Preferably, described groove outer wall is provided with squamous projection.
During work, the plush copper of plug is inserted in the groove of joint, owing to being provided with the rubber ring with groove clearance fit in plush copper in groove, so plush copper and rubber ring are interference fit, when plush copper moves to rubber ring and slot fit, and rubber ring and groove clearance fit.
Groove realizes clamping the plush copper of plug by rubber ring, ensures the stability that inserted link is connected with extension bar.
Squamous projection on groove outer wall increases friction force during hand contact, facilitates during grafting and exerts a force.
Compared with prior art, tool has the following advantages the utility model: structure is simple, makes the thread connecting mode of insulating bar of the prior art into inserting mode, and groove realizes clamping the plush copper of plug by rubber ring, ensures the stability that inserted link is connected with extension bar.Effectively easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of extension bar in specific embodiment;
Fig. 2 is the structural representation of inserted link in specific embodiment;
Fig. 3 is the structural representation of plug-in type insulation bar in specific embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, plug-in type insulation bar, comprises inserted link 5 and extension bar 1, inserted link 5 end is fixedly connected with plug 6, and extension bar 1 end is fixedly connected with joint 2, and the plush copper 8 of plug 6 and the groove 3 of joint 2 coordinate, plush copper 8 is provided with groove 7, is provided with rubber ring in groove 3, rubber ring and groove 7 clearance fit.The squamous projection 4 that groove 3 outer wall is provided with.
During work, the plush copper 8 of plug 6 is inserted in the groove 3 of joint 2, owing to being provided with the rubber ring with groove 7 clearance fit in plush copper 8 in groove 3, so plush copper 8 and rubber ring are interference fit, when plush copper 8 move to rubber ring coordinate with groove 7 time, rubber ring and groove 7 clearance fit.
Groove 3 realizes clamping the plush copper 8 of plug 6 by rubber ring, ensures the stability that inserted link 5 is connected with extension bar 1.
Squamous projection 4 on groove 3 outer wall increases friction force during hand contact, facilitates during grafting and exerts a force.
